Fixes the OEM boost leak | BIG Aftermarket Turbo Ready
Ditch your VB WRX’ leaky factory turbo inlet and upgrade to the OVERTAKE Aluminum BIG TURBO Inlet. Designed for 2022+ Subaru WRX' with larger aftermarket turbos, this high-strength aluminum piece increases airflow and improves on two big flaws in the factory inlet, allowing for superior intake temperatures and better boost response.
If you are running an upgraded turbocharger on your FA24, this option is perfect for you! Our standard 2022+ WRX Aluminum Turbo Inlet is designed around the stock inlet diameter of 49.5mm, but we have opened up the BT Version turbo flange to 54.5mm to account for larger aftermarket turbochargers like the Boost Lab BL54XR.
Key Benefits:
- 54.5 mm turbo inlet diameter - perfect match for upgraded aftermarket turbochargers like the BL45XR
-
Eliminates persistent boost leak that is present with the OEM Subaru inlet
-
No more coolant heating up the air entering your engine
-
Ensures consistent, metered airflow for better engine efficiency
-
Supports future intake upgrades for even more performance
The factory inlet is aluminum, how is OVERTAKE's any different?
Modern vehicles must prevent fuel vapors from escaping the gas tank, instead routing them to the engine so they can be burned off. When the engine is off, the entire system is sealed - hence the importance of a good gas-cap seal. At idle and under vacuum (no boost), a purge solenoid periodically opens and draws vapors directly into the intake manifold. Under light boost (0–4 psi), manifold pressure is too high to draw vapors in, so the solenoid instead routes them to the turbo inlet, where the natural pressure drop through the air intake creates enough suction. However, there is a flaw in this design. The EVAP sensor is located far away from the inlet and there is a long hose run between the two. This can lead to weak readings at the sensor. To remedy this, Subaru introduced a "band-aid" fix by drilling a 4mm hole into the turbo’s compressor housing feeding a venturi-style “ejector.” This intentional boost leak increases airflow through a small channel on the factory inlet, generating an artificial vacuum so the sensor always detects the expected pressure drop while vapors continue entering the turbo.
At wide-open throttle, the purge solenoid closes, holding the vapors in the tank, but the "ejector" continues leaking boost across the venturi into the turbo inlet. As a result, the turbo must spin faster to maintain target boost, raising charge temperatures, reducing intercooler efficiency, and limiting top-end airflow and boost potential. As a precaution, Subaru circulates coolant under the turbo inlet to keep the venturi from freezing, which would disable the EVAP system entirely. This coolant flow drastically heats up the factory turbo inlet to around 200 degrees Fahrenheit, which in-turn heats the air entering your turbo, leading to decreased performance potential.
As an alternative, the OVERTAKE Turbo Inlet utilizes the engine’s vacuum pump as a direct source to constantly supply only the necessary vacuum level, and places the source closer to the sensor. This pump is only utilized for the power braking system in the factory setup, so as to ensure our kit does not hinder braking performance at all, we include an inline restrictor pill to limit the vacuum levels to the required amount for the sensor to read properly. This preserves proper fuel vapor management, without relying on Subaru’s built-in boost leak. Since we have eliminated the potential for the small ejector orifice to freeze over, we can also bypass the coolant loop through the inlet, which also greatly improves performance potential by allowing fresh, cool air from your intake to enter the compressor side of the turbocharger.
On top of all of this, the factory Subaru turbo inlet features a couple of internal pockets which are meant to dampen induction sound and increase surface area for inlet warming. These pockets also greatly disrupt the air entering your turbocharger. Our inlet ditches them, allowing for a smooth path of flow and increased intake air velocity.

Came with everything I need for the install including extra fuel line and pre-cut pieces for the detail work so I don't have to cut and reuse the OEM line. Great company! I'm really glad they're out here adding to the aftermarket support and doing it correctly.
Install was easy and it came with everything you could possibly need. Packaging was top notch and shipping time was fast. Noticeable upgrade for the outback wilderness. Great product!
Packaged great, instructional video was spot on, and it arrived in the stated time period which was quick. What I didn’t like. I wrote Overtake asking about what might be a damaged product and received no reply. I can’t share the picture here, but basically the inside of this turbo inlet was not smooth. It looked like several large gouges had been made. The largest was about half a thumb nail in diameter, probably no more than 1/16in in depth. I sent the picture along with my email. There’s always the chance that I missed the email, but I’ve received several promotional emails from Overtake, as well as the updates I was given on the package, so I’d say emails working just fine. At time of writing, it’s been two weeks ago that I sent the message. I haven’t had the chance to run the car yet because I’m waiting on parts from another performance parts dealer, so I’m still unsure of the parts effectiveness.
Nathan, I wanted to let you know that I emailed you immediately when I saw this review (see below from Friday 6/26), but I also want to post a response here in case you didn't see that email come through. In any case, get back to my on help@overtakeusa.com so we can take care of things. Thanks!
'Hey Nathan, hope all is well! I was going through reviews from the past 24 hours just now and yours caught my attention. First of all, thank you for taking the time to write that up and for all the positive notes. I am surprised to hear about the negative part of your experience however, as above all else we pride ourselves in our customer service and making right any issues that our customers experience. If you didn't get a response from us, chances are some the communication got disconnected somehow. I'd like to start first with investigating where that disconnect was.
Did you send your original email from this same address [ncain87@outlook.com]?
What day was it sent on?
I ran your email through search and I'm not seeing any messages, including in our spam box. Could you do me a favor and double-check that you did indeed send the original to [help@overtakeusa.com] with no misspells? Thank you!!

The inlet is well designed and extremely well manufactured and the kit has what you need to make it work. It was a big job for me and a bud. The evap system fittings can be a serious PITA, though the install of the inlet itself was very simple. We did a intake and this inlet in about six hours but we had a lift. I would budget a lot of time for this guy.
That said the inlet works great and I do consider it worth the effort.
Install was pretty simple. I would say you can definitely feel a difference in boost with having the factory leak eliminated.
Loving the new turbo intake! Great quality! Can’t wait to touch up the tune to see what we gain from this part.
Vaccum lines are a pita to deal with. That was the longest part of the install. Tip: Measure and cut the hose that will have the brass pill. Then install the pill outside of the car (back saver)with a little silicone grease in the hose. Make sure the pill slides in straight. It has a tendency to turn while pushing inside the hose. Slide the hose back on and under the manifold and install. Almost impossible to stuff that pill in without some lube.
Hadn’t had a chance to install it yet, but shipping and delivery were top notch. Packaged very well and shipped almost immediately after ordering. Opening it, I could tell the piece was quality built, all hoses are pirelli. No shortcuts. Great group of guys. Thanks a lot!
Good quality. Can’t wait to install!
Beautifully machined piece with a pretty simple install. The vacuum hose part of the install is probably the hardest part and that’s only because of how tight the fittings have to be. Solo, took around 2 hours to complete without a lift
Amazing product with a very easy install
Looks and feels like a great product. The tall tell will be once I get it installed. I’m sure it will stand up to what overtake is!! Thanks fellas!!
Can’t wait to put it on my car!
I had the opportunity to hop in the group buy and get my hands on one of these units. Install paired with the video is perfect for clearing up any questions you may have diving into this project. The attention to detail not just in the part but also packaging is great. The sticker for the restrictor pill on the bag saved me because mine was sure enough lodged in the union. Also I have an ETS intake which had absolutely zero interference issues and pairs nicely for a clean look that no one will ever see. Thank you for making a quality product and I look forward to more in the future.
Improve reliability of an OEM part plus make the path towards the turbo smoother. Pairs well with a Torque Solution Intake Tube and a Blitz intake.
Love the sound.
The best product on the market for the VB WRX, such a bang for your buck.
haven't installed yet but it looks phenomenal and much better than the rubber/silicone ones from Perrin
Perfectly fits new IAG 600 ball bearing turbo! Thanks Overtake!
Went together as designed, all parts included, well thought out kit. Went with this to fix the boost leak and heated inlet issue. Did notice boost coming on earlier, probably as a result of not bleeding back to the ejector for the evap. Getting to boost target faster, feels like better throttle response.
nice inlet , easy to install, appears to be well manufactured, extra o rings included is a bonus if You need them. Would definitely recommend!
Easy install, great product. Bolt-on fit with no issues. Immediately felt the difference in throttle response and boost. Solid aluminum construction, fixes everything wrong with the factory inlet. No-brainer upgrade for any WRX owner.
I would say on a 2024 TR it's about a 4/5 to install. Especially if you have the optional front flat bottom that routes cool air to the trans. Takes another 20 min on top of that.
